We present the results of 450 and 850 \mu m continuum mapping of the H ii region KR 140 using the SCUBA instrument on the JCMT .
KR 140 is a small ( 5.7 pc diameter ) H ii region at a distance of 2.3 \pm 0.3 kpc .
Five of the six IRAS point sources near KR 140 were mapped in this study .
Our analysis shows that two of these IRAS sources are embedded late B type stars lying well outside the H ii region , two are a part of the dust shell surrounding the H ii region , and one is the combined emission from an ensemble of smaller sources unresolved by IRAS .
We have discovered a number of relatively cold submillimeter sources not visible in the IRAS data , ranging in size from 0.2 to 0.7 pc and in mass from 0.5 to 130 M _ { \odot } .
The distribution of masses for all sources is well characterized by a power law N ( > M ) \propto M ^ { - \alpha } with \alpha = 0.5 \pm 0.04 , in agreement with the typical mass function for clumped structures of this scale in molecular clouds .
Several of the submillimeter sources are found at the H ii–molecular gas interface and have probably been formed as the result of the expansion of the H ii region .
Many of the submillimeter sources we detect are gravitationally bound and most of these follow a mass–size relationship expected for objects in virial equilibrium with non-thermal pressure support .
Upon the loss of non-thermal support they could be sites of star formation .
Along with the two B stars that we have identified as possible cluster members along with VES 735 , we argue that five nearby highly-reddened stars are in a pre-main-sequence stage of evolution .
